Advice on low icp on hot start

[fatheadon1]

Hello guys my 05 is acting up on hot starts its fine when cold but when hot I'm only seeing 300-350 of the 500 psi needed. I'm pretty sure this means my dummy plugs or stand pipes are leaking even tho they were replaced in summer. I need advice weather to swap them an take the chance of that not being the problem or leave it and hope the truck make it threw the next 2 snow storms "this is a plow an salt truck" please let me know you Opinion on if I should leave well enough alone or dig in an pressure test it an pull it apart the day before Xmas when the dealer is not open to get parts. I do have new dummy plugs and stand pipes from another project

I wouldn't take chances with it. It will eventually not start at all and leave you stranded. Did you replace the STC fitting when you did the stand pipes and dummy plugs?

I did everything at once from the headgaskets up. I got rebuilt injectors from warrens even tho mine were good I wanted to freshen then. When I got everything back together new headgaskets,studs,injectors, ipr screen oil cooler update, egr blocked, standpipes dummy plugs, stc new turbo an lines. Fired the truck up. Bad injector code for cyl8 got a another injector from warrens the fire it up got a code for cyl 6 swaped that one then 4 went out so I told him send me 2 so I could finish that side. I did that and at that time I put in another new stand pipe even tho the one that i was replacing was not even 2 weeks old I did not want problems. Now I have problems and it freezing cold out. I have the Adapter to put air to the icp fitting. And the tool to hook up and cycle the ipr but like I said it cold I'd prefer to just swap the dummy plug and stand pipe. But I guess I need to test it fix the problem and send warrens a bill for my troubles.

That's kinda weird that every injector that went was on the drivers side.

When he got them back and pulled them apart cyl 6-8 never fired the first raplacement for cyl 8 actully never fired also. so he sent another one then cyl 4 the oring failed on top of the injector where it meets the oil rail so I swaped #2 just to be safe. This has been a night mare to say the least. Even sader is the truck had 140000 miles never an injector or high pressure oil leak till I put crap parts in.

I feel your pain. I had same kinda luck with my trans. Whole process to a year to get sorted out. You might have already tried, but when it won't start have you unplugged the ICP and tried it?

[fatheadon1]

Yes sir first thing I tried. To bad it could not be that simple.

Usually never is.

you have the fitting to air it up. i highly doubt it is going to be any updated hpo parts. i have never ever seen them fail..yet. and have seen a lot of these trucks.
air it up. it's probably an injector o ring. especially considering the injectors that are in there.
do you have your old ones? or did you return them for core? (i really hope not, since they sound like they were perfectly good injectors)

If it was still summer I'd test it an find the leak but with the weather being cold I figured I'd poll you guys an I guess I gotta test it in the cold. No I don't have the old one or they would have been back in after the first bad one. The truck only has 2500 miles on it since the refresh. So this all sucks.
